|
|
|
|
dnl Macro to add for using GNU gettext.
|
|
|
|
dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
|
|
dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
|
|
dnl default (if it is not specified or empty) is 'no-libtool'.
|
|
dnl INTLSYMBOL should be 'external' for packages with no intl directory,
|
|
dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
|
|
dnl If INTLSYMBOL is 'use-libtool', then a libtool library
|
|
dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
|
|
dnl depending on --{enable,disable}-{shared,static} and on the presence of
|
|
dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
|
|
dnl $(top_builddir)/intl/libintl.a will be created.
|
|
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
|
|
dnl implementations (in libc or libintl) without the ngettext() function
|
|
dnl will be ignored. If NEEDSYMBOL is specified and is
|
|
dnl 'need-formatstring-macros', then GNU gettext implementations that don't
|
|
dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
|
|
dnl INTLDIR is used to find the intl libraries. If empty,
|
|
dnl the value `$(top_builddir)/intl/' is used.
|
|
dnl
|
|
dnl The result of the configuration is one of three cases:
|
|
dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
|
|
dnl and used.
|
|
dnl Catalog format: GNU --> install in $(datadir)
|
|
dnl Catalog extension: .mo after installation, .gmo in source tree
|
|
dnl 2) GNU gettext has been found in the system's C library.
|
|
dnl Catalog format: GNU --> install in $(datadir)
|
|
dnl Catalog extension: .mo after installation, .gmo in source tree
|
|
dnl 3) No internationalization, always use English msgid.
|
|
dnl Catalog format: none
|
|
dnl Catalog extension: none
|
|
dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
|
|
dnl The use of .gmo is historical (it was needed to avoid overwriting the
|
|
dnl GNU format catalogs when building on a platform with an X/Open gettext),
|
|
dnl but we keep it in order not to force irrelevant filename changes on the
|
|
dnl maintainers.
